Virtual memory is used in Windows architecture because of the following reasons:

a.    The use of Virtual memory is to increase the size of the memory more than you have the memory in your physical system.

b.    The process which uses virtual memory cannot access other process’s memory, by this way it keeps the processes secure from another process.

c.    The pages which are placed in the virtual memory are having their own setting that agrees the protection which provide to the applications.

d.    The inactive memory which is for a longer time period will be stored in some regions which can be stored to the page-file or paged out.

e.    On demand the stored pages can be retrieved that is each time the system will need it, it can access it.
